Authorities say Devante Blackwood, 18, shot a 32-year-old man in the arm during a drug deal gone bad on March 13.

STATEN ISLAND, N.Y. -- An 18-year-old from Brooklyn who’s already amassed a lengthy arrest record is accused of shooting a 32-year-old man in the arm during a drug deal gone bad last month.

Police had been looking to question Devante Blackwood, 18, about the shooting, which took place on Kingsley Place in West Brighton at about 10:25 p.m. March 13.

On Thursday, they got their chance, when they spotted him at 4 p.m. on the corner of Jersey Street and Brighton Avenue, authorities allege.

He had marijuana and a knife in his pocket, police allege, and when he was brought back to the 120th Precinct stationhouse in St. George, police arrested him in connection with the shooting.

Blackwood has eight prior arrests on his record, according to a law enforcement source, including a February 2013 prison contraband charge filed against him in the Bronx while he was locked up awaiting prosecution on a criminal contempt case.

He ended up convicted of first-degree knowingly making or possessing dangerous contraband in prison last July, and received a one-year jail term.

Blackwood is now charged with first- and second-degree assault, second- and third-degree criminal possession of a weapon, criminal possession of a firearm, fifth-degree criminal possession of marijuana, unlawful possession of marijuana, and possession of knives or instruments, according to information from District Attorney Daniel Donovan’s office.

He was arraigned in Stapleton Criminal Court Saturday and ordered held on $100,000 bail until his next appearance May 9.
